[Qemu-devel] [PATCH v2 0/3] Replace 9p debug infrastructure with Qemu Tr

From: Harsh Prateek Bora
Subject: [Qemu-devel] [PATCH v2 0/3] Replace 9p debug infrastructure with Qemu Tracing
Date: Fri, 30 Sep 2011 16:06:12 +0530

This patchset introduces Qemu Tracing to 9p pdu handlers and removes the
existing debug infrastructure which became less meaningful after the
introduction of coroutines. With the existing debug infra, parallel
operations creates a messy output and filtering becomes difficult.

With Qemu tracing in place, we can selectively enable/disable trace-events
and the trace log can be further pretty-printed/filtered using an analysis

Harsh Prateek Bora (3):
  hw/9pfs: Introduce tracing for 9p pdu handlers
  hw/9pfs: Remove virtio-9p-debug.* infra to be replaced by Qemu
  scripts: Simpletrace log analysis script for pretty-printing 9p log.
